<a href="Context.html">Context</a> allows the use of a compatible
middleware at different points in a request handling stack. A compatible
middleware must define <a href="Context.html#M000022">context</a> which
should take the arguments env and app. The first of which would be the
request environment. The second of which would be the rack application that
the request would be forwarded to.
